We have a MRF1K50H-TF4, how can we setup the board connection?

I do not know to connect the DC voltage supply. The board has two green and two red ports, and another two black(ground?) ports. None of the ports are labeled and I could not find a document that explains the connections. Thanks.

Power-Up Sequence1. Terminate the RF input and output with 50 Ohm impedances: no RF signal applied.2. Dial all Vgs for minimum voltage.3. Set-up Vds over-current protection at the max expected level (~40A). Apply 50V Vds supply across the VDD and GND terminals.4. Slowly dial-up Vgs until the expected portion of IDQ is seen flowing from Vds. The order of adjustment is not important.6. Apply RF signal and load.
